While reading Sam Gentile’s blog today I came across an article regarding the SCBAT (Smart Client Baseline Architecture Toolkit) and GAT (Guidance Automation Toolkit). I was also discussing this stuff this morning with my friend and collegue Marc. In any case - this stuff reminds me of something I had advised doing (and have begun doing) for a current project. It also reminds me of something in Rails.

The essence of all of this stuff:

You have some application patterns, structures and practices. You want to create all the ’stuff’ you need to use the architecture pattern effectively and efficently, with as little confusion as possible.

For example:

In the now famed Rails web development framework - when you want to create a new project, new view/ controller etc, you just issue some command line .. commands.

For example - to create a new application you can issue a command like:

rails path/to/your/new/application

This will create the folders, base files, etc for your new web application: folders for views, controllers, models, etc. You can also use the rails generate command to create new controllers etc. like:

rails script/generate controller SomeController

Now you have the basics of your Rails application.

SCBAT with GAT

Now - looking at the SCBAT - these great fellows are trying to do is to allow you to enter some data - and it will spit out all of the folders, code etc to make a compliant CAB application. This automates away all of the grunt work, it makes it clear what is needed and it provides the guidance needed to use the frameworks. This is what Sam is talking about in his post here. Cool stuff - making it easier for the team to work effectively with the frameworks.

Frameworks/ System architectures for non-trivial applications are complex. It is a fact of programming life. That being said - doing as much ‘Guidance Automation’ as possible sets the team up for success and takes away increasing amounts of potential error.

Prototype Spiked for a current project as Guidance Automation

I will be leaving my current project (a credit derivative trading smart client application) in 6 weeks. I will be going to a new project (FX options trading stuff). As I have been trying to set up the team I am leaving behind up for continued success using the application infrastructure we have developed - I considered making a custom sort of code generator that functions as these other GAT type things/ Rails type things do… it would take the basic data and go create all the classes, events, folders, etc needed to use the framework effectively.

A screenshot of the basic code generator.

In a few hours I was able to create an application that would take in the information about what the View was to do - and to automate the creation of many classes needed. Since we are using a Model/ View/ Presenter pattern where the View communicates with the Controller via events, there is a set of pattern classes that we can simply create if we know what the view/ controller are trying to do. Hopefully before I leave here - I will be able to leave the team with their own custom Guidance Automation type applicatio that will help keep them on track. This was in truth inspired by how rails works. I am looking forward to using CAB, SCBAT and enabling more and more code generation and other types of guidance automation.
